In the production process of Polypropylene (PP) fibers,Polypropylene yarn spinning oil plays an indispensable role. This specially designed treatment agent for polypropylene fibers is like the "blood" of the production line, directly affecting the smoothness of the spinning process and the quality of the final fibers.

Unique requirements for Polypropylene yarn spinning oil

Unlike common spinning oil agents, Polypropylene yarn spinning oil requires a specially formulated design based on the characteristics of PP materials. Due to the strong non-polar molecular structure of polypropylene and the low surface energy of the fibers, conventional oiling agents are difficult to effectively wet and spread them. Therefore, high-quality PP spinning oil must address the following key issues:

Super strong wetting ability: A specially designed surfactant system ensures complete wetting of the fiber surface within milliseconds

Precise friction control: The dynamic friction coefficient should be controlled within the range of 0.20 to 0.35, and the static friction coefficient should be maintained between 0.25 and 0.40

Excellent thermal stability: It does not decompose, volatilize or coke at the PP spinning temperature (typically 200-300℃)

In-depth Analysis of the Core Functions of Polypropylene yarn spinning oil:

In actual production, high-quality Polypropylene yarn spinning oil needs to achieve an exact balance of four major functions:

Lubrication guarantee: Effectively reduce the friction between the fibers and the guide wire, as well as the friction disc, keeping the breakage rate below 1%

Bundle control: Ensure the bundling property of single filaments, prevent filament scattering, and at the same time ensure the smooth progress of subsequent processes

Anti-static protection: The surface resistance needs to be controlled within the range of 10^8-10^9Ω to completely eliminate the trouble of static electricity

Adaptive adjustment: Automatically adjust the oil film strength according to the spinning speed (typically 1000-3500m/min)
